Hi,
Remaining two days hope they need to support from home ? I presume so !
You can make simple circular.
Please refer the following.
Dear Employees,
Due to current ongoing project requirement it has been decided that all employees should support from office for 3 days in week and remaining 2 days can support from home. So please plan accordingly. Either you can work on Tuesday, Thursday, Friday or Monday , Wednesday, Friday.
All requested to confirm their choice of 3 days as above .
Feel free to contact HR Dept for any questions.
Regards
HR Team
